    Alain Bertaud, until recently Principal Urban Planner at the World Bank, is an independent consultant. Stephen Malpezzi is Professor, and Wangard Faculty Scholar, at the Department of Real Estate and Urban Land Economics, and an associate member of the Department of Urban and Regional Planning, of the University of Wisconsin-Madison.
    Comments and criticisms are particularly welcome. We have received useful comments from numerous colleagues, including Robert Buckley, Paul Chesire, Peter Colwell, Peter Englund, Roy Gilbert, Daniela Gressani, Gregory Ingram, Christine Kessides, Kyung-Hwan Kim, Somik Lall, Bertrand Renaud, Margret Thalwitz, Bengt Turner, Lee Travers, Anthony Yezer, and participants in a seminar presented to the University of Uppsala’s Center for Housing Research in Gävle, Sweden. Yongping Liang drafted the second appendix. These colleagues bear no responsibility for remaining shortcomings.
